is_live meint nur "laeuft gerade als Stream" — eine Konzert-AUFNAHME kam
ungehindert durch und landete als Albumtrack in der Bibliothek ("Dat Adam - Ufo
Video Days 2015 Live" auf dem echten Kuenstlerkanal, Dauer im Fenster). Der
Variantenfilter bekommt daher eine live-Regel. Sie schaltet sich ab, wenn der
gesuchte Titel selbst live enthaelt; die Pruefung nutzt \blive\b statt includes,
sonst wuerde "deliver" die Regel aushebeln. Drei Tests dazu.
